[BUG] no permissions for [] and User [name=admin, backend_roles=[admin], requestedTenant=null] on .opensearch-cluster-control

[boomcubist]

Describe the bug

Following upgrade to 2.18.0 on a single node cluster the .opensearch-cluster-control has number_of_replicas: "1".

Attempting to change this to number_of_replicas: "0" returns the following error even for the initial admin user.

{
"error": {
"root_cause": [
{
"type": "security_exception",
"reason": "no permissions for [] and User [name=admin, backend_roles=[admin], requestedTenant=null]"
}
],
"type": "security_exception",
"reason": "no permissions for [] and User [name=admin, backend_roles=[admin], requestedTenant=null]"
},
"status": 403
}
